I’m a 40 year old male, 5’5" (1.4m) and 126 lbs (57kg).
I’ve been cycling in earnest since February, having started with Peloton. I ultimately made the jump to riding on the road in March, and have been riding with increasing seriousness since then - including some on Zwift before I settled in with SUF.
My first FTP test with Peloton (back in May) had me at 147. My first Half Monty on SUF was in early August, and it showed my FTP as 117. The scared me, cuz that seems really low. But onward we went.
Since then I’ve been riding pretty consistently 5-6 hrs/week, and have been able to tackle ~35 mile rides with >2000’ of climbing as I build up to longer rides. I’ve also been doing the SUF Novice Training Plan (with Strength) for the last month or so, and have been eating primarily plant-based foods since September 1.
I did another Half Monty today. And my FTP decreased to 116. My Garmin watch (which I log everything through) auto-detected a new FTP during the ride, but called it 144.
1.) Doesn’t 116 and 117 seem ridiculously low? I’m a little guy, but I’m not sure it makes a difference in this metric. I average 17-18 mph on moderately hilly rides, and 13 mph on very hilly rides. Maybe I really am just that weak? I guess the silver lining would be that I have plenty of room to improve.
2.) Why is there such a disparity between the Peloton/Garmin FTPs and SUF’s? I have two data points now that suggest a gap of ~30W.
3.) Should I be worried that I’m not improving? I’m riding more than I have in the past - though I’ll admit that some of the adjusted Novice rides are too easy and I find myself needing to manually crank things up a little.
Thanks for any insights. This community (and this ecosystem) is awesome.
